Windows programming code

Most samples still function credit to Microsoft and their emphasis on backwards compatibility , but some do not, particularly in Chapter 16 due to the requirement of hardware with bit display pallete. Needless to say, decades after these samples were written, such hardware now exists mostly as a historical note of a bygone era in computing. Some samples generate deprecation and security warnings upon compilation, and I recommend you heed those warnings if you intend to use any code in production.

When using any Win32 code from this repo in production, always consult the Windows API Index for relevant and updated API usage notes, as some APIs may have since been deprecated or had their behaviour modified in newer versions of Windows. Skip to content. Star Branches Tags. Some of this overlap is simply due to the history of the Windows APIs.

The types listed here have fixed size, and the sizes are the same in both bit and applications. The header file WinDef. Therefore, you should always write this:. Windows defines many data types of the form pointer-to-X. These usually have the prefix P- or LP- in the name. The following variable declarations are equivalent. On bit architectures bit Windows there are 2 types of pointers, P for "pointer" and LP stands for "long pointer".

Long pointers also called far pointers were needed to address memory ranges outside of the current segment. The LP prefix has been preserved to make it easier to port bit code to bit Windows. Today there is no distinction, and these pointer types are all equivalent. For more details about these options, see this article. Win32 APIs exist for many features and technologies in Windows 10, including core user interface and windowing APIs, audio and graphics, and networking.

For guidance and code samples about using these APIs, see our features and technologies index. Skip to main content. This browser is no longer supported. Download Microsoft Edge More info. Contents Exit focus mode. Is this page helpful? UWP Free. MarkPad Free.
